TYPES OF SEPARATION TECHNI

A mixture of iron filings and sand needs to be separated. What method is BEST? Magnetic separation

Water needs to be poured away from boiled rice. What method is BEST? Decanting

Sand needs to be separated from water using a filter. What method is BEST? Filtration separation

Salt needs to be recovered from saltwater, and the water does not need to be collected. What method is BEST? Evaporation

Two liquids have different boiling points and need to be separated. What method is BEST? Distillation

Oil and water form separate layers because they have different densities. What method is BEST? Density separation

A sample needs to be separated by spinning it rapidly. What method is BEST? Centrifuge

Different dyes in ink need to be separated based on how far they travel across paper. What method is BEST? Paper chromatography

Two dissolved solids have different solubilities and need to be separated by forming crystals. What method is BEST? Fractional crystallization

Large pieces of gravel need to be physically separated from sand using a tool. What method is BEST? Mechanical separation

A magnet is used to remove iron from a mixture. What method is being used? Magnetic separation

A liquid is carefully poured away from a solid that has settled at the bottom. What method is being used? Decanting

A filter traps a solid while the liquid passes through. What method is being used? Filtration separation

A solution is heated so the liquid turns into vapor, leaving the solid behind. What method is being used? Evaporation

A liquid is boiled and then the vapor is cooled back into a liquid to collect it. What method is being used? Distillation

Two liquids separate into layers because one is more dense than the other. What type of separation is being used? Density separation

A machine spins a mixture very quickly to separate its components. What method is being used? Centrifuge

Colored substances move different distances through paper with a solvent. What method is being used? Paper chromatography

A solution is cooled so substances with different solubilities form crystals at different times. What method is being used? Fractional crystallization

A mixture is separated by physically picking, sorting, or using a tool to remove its components. What method is being used? Mechanical separation

Which method uses a magnet to separate a mixture? Magnetic separation

Which method involves carefully pouring one liquid away from a settled solid? Decanting

Which method uses a filter to separate an insoluble solid from a liquid? Filtration separation

Which method removes a liquid by changing it into a gas and leaves the dissolved solid behind? Evaporation

Which method uses differences in boiling points? Distillation

Which method uses differences in density to separate components? Density separation

Which method uses rapid spinning to separate components? Centrifuge

Which method separates substances based on how far they travel through paper? Paper chromatography

Which method uses differences in solubility to form crystals and separate substances? Fractional crystallization

Which general method uses physical actions or tools to separate parts of a mixture? Mechanical separation

What physical separation technique is BEST used to separate sand from a mixture of sand, salt, and water? Filtration separation

What physical property allows filtration to separate sand from saltwater? Particle size and the fact that sand is insoluble in water
